Funding will support the project team's small-scale research and development of a technology to enhance the power delivery system for laser drivers by leveraging efficient microwave sources in combination with electron beams to energize excimer gas lasers used in generating laser-based inertial fusion energy. Specifically, the project team will (1) develop simulation models to test and validate system function and metrics, (2) identify and procure components for an experimental system, (3) design experimental system with associated monitoring and diagnostic components, (4) develop experimental system, test and validate system performance, (5) based on performance results, design, construct, and validate a full hybrid pumping system, and (6) test and validate full hybrid pumping system to obtain performance targets. If successful, this project will result in a technology that will be applicable to deploying inertial fusion energy power plants by the mid-2030s, reducing dependence on foreign energy sources, and thereby increasing U.S. energy security.
